If you added more dogs, I would buy. I love Labradors personally their my favorite breed. Black labs, golden labs, big dumb chocolate labs (could just use same model with different skins, though Chocolate labs are usually a bit bigger). Huskies and German shepherds are up there too, beautiful dogs, and Rottweilers are the most bad ass. But we should not leave out Dobermans, Boxers and Pitbulls and maybe even Chihuahuas, Beagles, Jack Russel and Dachshunds or even a Schnauzer. But no Poodles. No one ever asked for poodles.
You what would be really cool? If there was a dog breeding system in the game, even if just really simple, Chihuahua plus Lab has a chance to produce a beagle or a jack Russel, A Doberman with a Chihuahua makes a Dachshund, A lab with a German Shepard makes a Doberman, A doberman with a Pitbull has a chance to make a Rottweiler or a Boxer, a Husky with a Doberman or a Lab makes a German shepherd or a Greyhound, A Lab+Greyhound=Dalmatian or Doberman, Husky+Chihuahua or Boxer+Jack Russel makes a Schnauzer or a Dalmatian, Labrador+Husky=German Shepherd, etc.... maybe...something simple like that. Maybe even start with four base breeds. Husky. Labrador. Pitbull. Chihuahua.
